Salamandastron, ancestral home of the Badger Lords is under threat from an enemy whose power is absolute and whose evil knows no bounds. Ungatt Trunn can make the stars fall from the sky, the very earth shake underfoot, and with a horde of vermin as numerous as the leaves in autumn, the wildcat appears unstoppable. The mountain's defences are weak. Who can save it now? Salamandastron's only hope is a badger, Lord Brocktree who is drawn to the fortress by a sense of destiny. If he is to rescue the mountain from the vermin rule, Brocktree must raise an army capable of combating Trunn's formidable Blue Hordes.
